Well, This is a very personal topic and as you see, there are a myriad of responses, none are wrong. I personally went through a similar ordeal in trying to choose a folder and an EDC fixed blade with a certain budget in mind.....you can go crazy and spend hundreds of Dollars on super duper custom-cum-special-steel knives, ATS34,....etc etc etc or whatever.
I eventually settled for a CRKT Polkowski-Kasper Companion. Check it out at
www.crkt.com. It has a 4" blade of AUS6 steel...this is misquoted on the web site...a ruler does not lie...they claim it is smaller. It retails at stores for under US$40 and it is the best bang for your buck in an EDC fixed blade period!!!! I also bought the CRKT Ryan 7 folder incidentally. Both knives cost me under the equivalent of US$90!!!
I researched this extensively with experts in both knives and self defense. This is what I gleaned from my research, which every forumite should bear in mind when it comes to "fighting" or "tactical" or "self defense" knives:
1. A fighting knife is the knife you have on you when you get into a fight.....period! BTW there is no such thing as a "fighting" knife.
2. It is highly unlikely...no it is virtually never going to happen that the average citizen is going to use any form of blade to cut someone else....on purpose that is.
3. The average citizen will never get to use a knife of any sort for self defense, or for fighting etc.
4. Blade steel is irrelevant for a knife to be used for cutting or stabbing someone else.....heck a plastic knife will achieve this...and yes, they are available, making airport security very nervous.
5. The terms "fighting" and "tactical" etc etc used for knives, are merely a marketing ploy by the maker/s. The real McCoys are only used by military, paramilitary etc. etc.
6. A gun is more effective and easier to carry for self defense than any knife could ever wish to be.
7. Knives are merely tools or ornaments or both.
8. Knives are appreciated for their form and shape.
9. Knives are important for people in general or else this forum would not exist
10. It gives people something else to collect...LOL. BTW I love knives and have many of my own including fixed blade and folders. This includes the ubiquitous Swiss Army Knife.....Swiss Champ.
